[Elecraft] K3 Poor RX on 17m

[Chris Page]

Can someone help me with a receive problem with my K3, 
please?

I use a K3 with Sub-RX and P3 for CW only with crystal FL1 
2.7k, FL2 1k, FL3 400Hz and FL4 250Hz filters, and over the 
past few weeks have noticed a deterioration in the RX 
performance just on 17m.  All the other bands are working 
fine and transmissions on 17m are fine.  If I switch to SSB 
on 17m, I hear CW signals that are not audible in CW Mode.

I would be grateful for any help and suggestions on what to 
check, please?

Thanks and 73 de Chris, G4BUE
